JOHN E. TAYLOR AND FRANK LASSIGNOIB, TO SAID SilVlAltll)v CAR-COUPLING.

To all whom t may concern.'

Be it known that we, JOHN H. TAYLOR and coupling that will be notable for its ease and positiveness of operation in both the coupling and uncouplingaction.

Another object is to provide a `coupling of the nature described wherein the tail of the usual, knuckle includes two portions lying in dierent horizontal planes, and a locking member adapted after the uncoupling operation to rest on the upper of the two `portions of the tail, the tail inthe coupling operationv passing from beneath the member topermit said member to drop to the locking position.

Another object is toprovide a structure inl a car coupling in which the knuckle will be positively thrown to the unlocking position with the least amount of-eifort, resting upon the knuckle while in the unlocked or open position, said locking me1nber upon movement of the knuckle to its coupling position being liberated to drop down into position to lock said knuckle.

Besides these objects the invention relates to certain details of construction to be pointed out herein and in the accompanying claims, aided, by the appended drawing, which shows the preferred embodiment of the invention, though it is to be understood that slight changes may be made, such as will fairly fall within the meaning of the invention and the scope of the claims,

Figure 1 is a yplan of the coupling, showing the knuckle in its open position.

Fig. 3 shows the knuckle and a part of the locking member in perspective.

Fig. 4 is an elevation of an, operating member shown in part section.

the latter y said part 10 extends Patented oet. i, lele.

of the draw-head showing the relation of the several operating parts therein.

1 is the draw-head including the usual shank. 2 for attachment to the car. Said draw-head in general outline and dimensions corresponds to those in common use but its cavity differs in its form to accommodate the form of knuckle, and the form of locking member included in my invention.

`The `cavity is denoted by the reference character 3 into which the knuckle extends. Thedrawehead has an upper and a lower extension 4 and 5 respectively, Fig. 6, between which is pivoted the said knuckle indicated as a whole by 6, the pivot member being indicated as a pin at 7.

`The outer coupling portion 8 of the knuckle is substantially identical in form with those now in almost universal use while that part within the draw-head comprises a tail piece whose longest measurement lies at a slight angle to the longest measurement of the described coupling portion 8, said angle being an acute one. Said tail piece comprises an upper and lower part 9 and 10,

' one offset from the other as clearly shown.

The part 9 is flat on its upper surface, its end surface by preference describing an arc struck from substantially the center of the pin'7 also by preference. The part 10 lies lower than the described part 9 and extends beyond the end thereof into a point 11 ,also laterally from the part 9. The rear edge of the part 10 or that facing the rear wall of the cavity is carried forward to or beyond the rear face of the part 9 substantially in the manner shown.

Thedescribed cavity 3 has a deepened rearwardly extending communicating cavity 12. 13 indicates as a whole a locking member shown in full in Fig. 5, lying in said cavity 12. It comprises an upper head por tion 14 including at one corner a point 14 and includes also at two of its sides opposite said point a depending extension 15 creating a cavity 16. f 1 is a depending finger at one corner of the `head 14 which curves forwardly substantiallyat an angle of 45o to the longitudinal line of 4the draw-head, slanting downward at an angle and terminating in a vertical portion 18. This finger is adapted to move vertically within a slot 19 in the bottom of said draw-head.

The locking member slidably fits the recess 12, being adapted to move vertically therein and has an upstandinof ear2( ).vf 2l i is an operating ,member *therefor n vertically.,` slidtbie wtliina hole 22^rr th'egtopiwall fof" the draw-head, Which operatingmemloer'is' 5 slotted at 237 a pin 24 in the ear 20 engag;
